"For about a month now, I've been having a problem with my Golf 4 AJM 4M that it starts very poorly, whether it's cold or warm. I've noticed that I no longer hear the fuel pump "whirring" when I turn the ignition on."
"Also, I occasionally experience extreme hesitations when I'm riding uphill at a low RPM, which wasn't happening before."
"Yesterday, I replaced the pre-pump with another one, but the same problems persist. Additionally, I disconnected the fuel line leading to the diesel filter and tried to start the engine, but no diesel is coming through."
Thanks for your reply. And no, I'm not listening to it anymore; I'd say it's not working.
I still need to check about the electricity; I'll do that tonight.
